我编写了一个批处理文件,我想用另一个.txt文件中的字符串覆盖键字符串。
目前它完全复制了新的File.txt文件,但没有用OldFile.txt文件中的字符串替换字符串。
File.txt文件中的字符串示例:
...
#密码
PWORD =#AccountName
帐户=#TownName
镇=#Postcode
邮政编码=#LocationChangedDate
LocationChanged =
我要替换的OldFile.txt文件中的字符串示例:
...
#密码
PWORD = ABC#AccountName
帐户= 123#TownName
镇= LDN#Postcode
邮政编码= WS77TP#LocationChangedDate
LocationChanged = 01/01/2015
有人可以指出我正确的方向或解释我犯错的地方吗?

我想我终于明白了......
它的作用:
_PWD
标记(变量)它的值为Pword=
,它会创建一个_PWDCONTENTS
变量,其内容为Pword=ABC
。CONTENTS
变量将转储到 OutFile.txt ,否则原始行。因为这发生在内部for
循环中,我不得不添加一些额外的逻辑(_WROTE
var)以避免多次写入相同的行。备注:
假设(除了做它应该做的事情之外)是“可配置的”(代码很复杂,它正朝着 meta :)前进,如果你愿意的话,意思是如果标记之间存在变化,则代码不应更改(代码更改,但仅在变量定义中不在功能部分)。让我详细说明一下:
Town=
字符串,那么您只需从_TOWN
移除_ALL
:set _ALL=_PWD _ACCT _POST _LOC
。set _NAME=Name=
并将其添加到_ALL
}:set _ALL=_PWD _ACCT _TOWN _POST _LOC _NAME
。作为间接后果,我没有专注于性能,所以它可能会运行缓慢。无论如何,我试图将磁盘访问(速度极慢)保持在最低限度(例如,当有2 for
循环时,迭代文件内容的循环 - 假设每次迭代都需要磁盘访问;这可能不是真的, Win 有IO缓冲 - 它是外部的。)
rem
。这是批处理代码:
@echo off
setlocal enabledelayedexpansion
set _INFILE="File.txt"
set _OUTFILE="NewFile.txt"
set _OLDFILE="OldFile.txt"
set _PWD=Pword=
set _ACCT=Account=
set _TOWN=Town=
set _POST=Postcode=
set _LOC=LocationChanged=
set _ALL=_PWD _ACCT _TOWN _POST _LOC

for %%g in (!_ALL!) do (
echo %%f | findstr /b /c:!%%g! 1>nul
if "!errorlevel!" equ "0" (
set %%gCONTENTS=%%f
)
)
)
copy nul %_OUTFILE%
echo Merging the old file contents into the new file...

if "!_WROTE!" equ "0" (

) else (
set _WROTE=0
)
)
rem copy /-y %_OUTFILE% %_INFILE%
@ EDIT0 :使用@StevoStephenson建议(作为问题代码段的一部分),我将(第二个)外部for
循环替换为('findstr /n "^^" !_INFILE!')
以包含空行,所以第3条评论不再适用(删除)。还进行了一些小的更改,以允许在其路径中包含 SPACE 的文件。

它并不完美,但这对你来说可能没问题:
@Echo Off
Setlocal EnableExtensions DisableDelayedExpansion
(Set InputFile=F:\EXCHANGE\3\Machine\File.txt)
(Set OutputFile=F:\EXCHANGE\3\File-New.txt)
(Set CopyFile=F:\EXCHANGE\3\OldMachine\OldFile.txt)
For /F "Delims=" %%I In (
'FindStr/B "Pword= Account= Town= LocationChanged= Postcode=" "%CopyFile%"'
) Do Set %%I
(For /F "Tokens=1-2* Delims=]=" %%I In ('Find /V /N ""^<"%InputFile%"') Do (
Echo(%%J|FindStr/B # || (If Defined %%J (Call Echo=%%J=%%%%J%%) Else (
If "%%J" NEq "" (Echo=%%J=%%K) Else (Echo=)))))>%OutputFile%
Timeout -1
EndLocal
Exit/B
我已离开删除并重命名,以便在最后添加。
答案 2 :(得分:0)
也许它就像这样
set CopyFile=oldfile.txt
set InputFile=newfile.txt
set str_search="Pword"
for /f "delims=" %%i in ('findstr %str_search% %copyfile%') do set str_replace=%%i
set str_replace="%str_replace%"
echo %str_search%
echo %str_replace%
pause
CALL :far %InputFile% %str_search% %str_replace%
EXIT /B 0
:far
setlocal enableextensions disabledelayedexpansion
set "search=%2"
set "replace=%3"
::remove quotes
set search=%search:"=%
set replace=%replace:"=%
echo %search%
echo %replace%
set "textFile=%1"
for /f "delims=" %%i in ('type "%textFile%" ^& break ^> "%textFile%" ') do (
set "line=%%i"
setlocal enabledelayedexpansion
set "line=!line:%search%=%replace%!"
>>"%textFile%" echo(!line!
endlocal
)
EXIT /B 0
在for /f "delims=" %%i in ('findstr %str_search% %copyfile%') do set str_replace=%%i
,您使用具有str_replace所需信息的变量编写该行。
之后,程序调用一个嵌入式查找和替换函数(:far
),我从Batch script to find and replace a string in text file without creating an extra output file for storing the modified file无耻地偷走了这个函数
此函数查找字符串“Pword”并将其替换为旧文件中的行find。
注意: 这并不能完全解决您的问题,因为您的新文件必须是这样的。
#Password
Pword
所以,如果你松开=
,它就会起作用,否则就不会。我希望这可以帮助您解决问题。
答案 3 :(得分:0)
此解决方案应该比其他解决方案快得多
它还会保留包含!
和^
。
只需要一次findstr
来收集所有单词的旧值
第二个findstr
确定infile
中需要更新的所有行(按行号)。
